UNITED ROBERT ASHLEY GRIM, OF SPRINGFIELD, OHIO.

SPECIFICATION forming part of Letters Patent No. 451,271, dated April28, 1891,

Application filed November 26, 1890. ySerial No. 372,708. (No model.)

To a/ZZ whom, it may concern,.-

Be it known that I, ROBERT ASHLEY Garn, a citizen of the United States,residing at Springfield, in the county of Clark and State of Ohio, haveinvented certain new and useful Improvements in Stoves, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

My invention relates to certain new and useful improvements incooking-stoves, the peculiarities of which will be hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, forming a part of this specification, andon which like reference-letters indicatecorrespondin g parts,

Figure l represents a perspective view of my improved stove, the brokenlines indicating how the top thereof may be increased in capacity; Fig.2, a vertical section through the stove, looking to the rear; Fig. 8, aside and partial sectional view of the same; and Fig. 4 a plan view ofthe false bottom, showing the deiiecting-guides.

The letter A designates a case, preferably of sheet metal, andconveniently riveted together, as shown in Fig. 1,to form a compactrectangular case. A cast-iron top Bis adapted to lit on said case and isprovided with a convenient number of holes and covers therefor in theusual manner. A stove-pipe C is fastened to the back of said casing andhas an opening D near the top of the stove closed by a damper operatedby a crank E on the outside thereof, in the usualway. A iirebox Fextends from the front to the rear of the casing near the top thereofand directly under the draft-opening D, before referred to. A grate-barG is pivoted or otherwise mounted therein and has an extension H,adapted to receive a handle for rocking the said grate or otherwiseshaking the same. Beneath the grate is located an ash pan I, mounted inslides or otherwise, so that it may be drawn out when desired. Y

The fire-box is fed from a front door J, having a check-draft openingJ', adjustable bythe usual slide, whereby coal or other fuel isintroduced upon the said grate. If desired,

however, the lire-box maybe fed through the top B.

On either side of the ash-pan and fire-box are located water-tanks K K',the sides and tops of which convenienly support the firebricks F orlining of the fire-box F. These tanks are conveniently connected by acrosspipe L, Figs. 2 and 3, and are supplied with water through a spoutM, extending outside of the casing. Below the water-tanks and ash-pan islocated the oven O, conveniently mounted upon the inclined partitionsP,sup ported by the false bottom Q, beneath which is the dead-air spaceseparating it from the floor. A door S in the front of said casing isadapted to close said oven, whichis conveniently provided with rests Tfor the support of the usual cross-shelves therein.

lt will be seen from Figs. 2 and 3 that the oven and tanks are separatedfrom the sides of the casing, leaving passages U, whereby the productsof combustion from the fire-box may be drawn downward under and aroundthe said oven and into the lower opening V in the stove-pipe C. Thisaction occurs when the top damper closes the opening D, and the draft isthus deflected from its direct passage to the chimney, so that it mustpass downward to the lower opening V.

The inclined partitions P are adapted to distribute hot air and gasesunder the whole bottom of the oven and prevent their rushing directlyinto the stove-pipe through the openingV without heating the front partof the bottom of said oven, as would be the case in the absence of theguides. If desiredthe sides of the casing may be provided with a liningW, of asbestus or other non-conducting material, to prevent theradiation of heat through said casing. The dead-air space R beforementioned serves the same purpose at the bottom of the casing.

It will be seen from Figs. 2 and 3 that the fire-box is small incomparison to the size of the oven. The passages U at the sides of theoven and the space at the bottom and back thereof present a largeheating-surface adapted to take from the products of combustion a largeamount of heat and uniformly heat the said oven.- lt will be observedthat the water-tanks K K and the ash-pan I before mentioned protect thetop of the oven from undue heat from the iire-boX, and the heated gases,having free access to all the walls of IOO fof the casing. In the usualform of stove' the oven except the front, uniformly heat the oven andsecure better results 'in cooking. This oven O is preferably adapted tobe removed from said casing by removing the false bottom Q. It is Vkeptfirmly pressed against the front of the casing by the springs a, Fig. 3,or otherwise, so as to allow no exit of gas into the oven between thefront of the casing and the walls thereof. lVhen it is necessary toremove the oven, the old one may thus be easily detached and the new oneinserted at small expense. A small opening b in the front of the casinggives access to the space between the bottom of the oven and the falsebottom Q, whereby the ashes or soot may be removed in the usual manner.This opening is nor-mally'closed by Aa slide or otherwise. The front ofthe casing is also provided with draft-openings c below the grate,closed by the slide d in the usual manner.

Vhile the lire-box has been described and capacity may be applied tothis casing, and i Fig. 2 shows aconvenient arrangement when this largertop is used. that these side holes will also receive the benefit of thefire, as the draft draws lthe products of combustion out sidewise intothe extension the draft from the grate has a tendency to 'avoid thelside holes. In this form all of the top is heated, and 4there is lessdifference in the amount of heat distributed to the holes. If desired,an additional water-tank g may be located under this extension fandconnected to the previously-mentioned tanks K K by a pipe Z. Thus alarge boiler capacity for hot water is provided, and a large ovenuniformly heated is secured by the use of a proportionately smallfire-box and `correspondingly small amount of fuel.

The compactness of this stove is apparent. Cheapness is secured by thesimplicity of construction, and it is specially adapted for use in'small kitchens or where space is limited, such as galleys on boardships and kitchens of railroad-cars.

From. the construction of the lire-box it will be seen that the draft isdirectly through the center from the front to the draft-opening D intothe chimney. This facilitates quick combustion in starting the fire, theheated gases from which may be instantly directed downward to heat theoven by turning the damper-handle E. If desired, thelower draftopening Vmay also be closed by a damper, as indicated by the dotted lines in Fig.3, in order to cause the entire draft to pass through the fire into thedraft-opening D in st-arting the fire.

It will be observed I-Iaving thus fully described my invention, what Iclaim as new, and desire to secure b Letters Patent, is-

l. In a stove, the combination, with a casing and a top plate` of aiire-box near said top plate, an oven within said casing provided with adoor and adapted to allow free access of the products of combustion toall sides thereof, except at the said door7 a nonconducting lining` toretain the heat within said casing, a iiue from near the bottom of saidcasing adapted to lead off the products of combustion, anddeflecting-partitions between said oven and casing adapted to spread outsaid products in contact with said oven and retard their escape throughsaid flue.

2. In a stove, the combination, with a casing and a top plate, of afire-box near said top pla-te, an upper ilu-e immediately adjacentthereto, an oven below said {ire-box having a door and mounted in saidcasing, so as to form passages for lthe products of combustion on allsides but one, inclined partitions in said passages to equalize thedistribution of heat, and a lower iiue from the last of said passages tolead off the said products `of combustion.

3. The combination, with a stovecasing of riveted sheet metal providedwith the usual cast top plate and pipe, of a fire-box near said topextending from the front to the back, an upper draft-opening at the rearof said box, lateral water-tanks next to saidlire-box, an oven supportedin said casing under said fire-box and water-tanks, so as to formpassages between its walls and the casing, a lower draft-opening to thesaid pipe, and delecting-partitions thereto, whereby the products ofcombustion pass out of the upper draft to startthe fire and may bedirected downward about said oven to .heat the same uniformly and out ofthelower draft-opening.

at. The combination, with a rectangular stove-casing of riveted sheetmetal and a castiron top plate, a fire-box under the same, lateralwater-tanks forming the sides of said fire-box, and supply and outletpipes for the water, of an oven below said tanks and rebox, mounted toform passages between the walls of the casing and the oven, and upperand lower draft-flue openings, one directly connected with the fire-boxand the other with said passages below the oven, whereby the draft maygo directly from the fire-box in starting the fire and then be deflectedlaterally to each side of the box and downward about said oven to thelower draft-opening.

In testimony whereof Iafixmysignature in presence of two witnesses.
